This might seem like a rather odd idea, but I was thinking about installing a Pioneer Appradio 2 to control my phone on my car stereo. I can't justify spending who knows what on installation costs when all I want is to hear my Pandora through my stereo and conveniently able to switch apps. Then I thought about a possible workaround, using my steering wheel. It has Volume/Channel up/down and a Mode button. Is there a way to integrate my steering wheel buttons into switching volume, changing tracks and switching modes while still being able to use it with my existing stereo? I have an AM/FM radio w/ CD player and also a tape deck. Is there a way to hook up a backup camera to your Smartphone via bluetooth? My current setup is Smartphone to Bluetooth to tape deck adapter to stereo. I had the car dock for my RAZR MAXX but the audio went bad on it.
